6 Claims.

My invention is an improvement in dumping receptacles and relates more particularly to that type of dumping receptacle which is used in connection with a. tilting vehicle body for conveying. and delivering batches of material. The present invention relates more particularly to such 'a receptacle which is adapted to retain its charge regardless of the position of the receptacle with respect to the vehicle body, until it is desired to release the charge and discharge the same into the body or a compartment theree of as when the vehicle body is tilted. The inveniurther relates to dumping receptacles of this type which may be handled conveniently in charging it with materials, or discharging its contents without the aid of latches or other locking devices.,

The invention is particularly well. adapted for use in connection with a tilting truck body for separately transporting or storing a mixture of inne, and; coarse aggregates, and the cement for aconcrete. batch, and for discharging the cement into or with the aggregates as they are discharged frcm the truck body.

It is one of the objects of my invention to so construct the receptacle and its mounting with respect to the vehicle body onwhich it is supported, that it will be unnecessary to employ :latching devicesl or locks to retain the receptacle, when loaded, in an upright position on thev vehicle body.

It is a further object of my invention to adequately protect materials such as cement, which may be carried by the receptacle, by preventing access of moisture into the interior of the receptacle, and at the Sametime to eliminate inter- .ierence or obstruction to the operation of the receptacle in. dumping. the material, or to interere with the loading of the receptacle.,

A. still further object of the invention resides in simplicity of construction and operation of the device and thereby materially reduce the cost Yof manufacturing of such articles without sacll'iiicing., strength or durability.

Another object ci my invention is to provide a simple mounting for receptacles of the above mentioned character whereby the said receptacles `may be quickly and removably mounted and supported upon the upper edges of the vehicle body sides, thus eliminating. the use of. cumbersome mounts or standards, and permitting at all times proper positioning of the receptacle on its suprt, A. still further' object 'of my invention is to pro- `vide a dumping receptacle which may be mounted on a vehicle body and which has freedom of movementbetween loading and discharging limits.

Other objects and advantages of my invention will become more apparent as the following description of one embodiment thereof progresses, 5r reference being made to the accompanying drawing in which like reference characters are employed' to designate like parts throughoutthe same.

In the drawing:

Figure 1 is a side elevation of an embodiment of my invention shown applied in'use on a tilting truck body. In this view the truck body is shown in solid lines in its normal horizontal position, the receptaclesbeing shown in full lines iii in Van upright position. In this same view the tilted position of the truck body is indicated in broken lines, and one of the receptacles in one of the compartments of the truck body is shown in its discharging position with the cover free 20 from the open end of the receptacle.

Figure 2 is a fragmentary side elevation of an apparatus embodying my invention and shows the dumping receptacle in its two limits of movement, that is, in charging position, and, in broken lines, in discharging position, and,

Figure 3 is a fragmentary front View of. one of the receptacles and illustrates one manner of mounting the same on the side walls of the vehicle body.

Referring now more particularly to the figures, I will proceed to describe the construction and operation of the embodiment of my invention shown inthese iigures,` although it will be understood that the embodiment shown is merely by way of illustration and I do not limit the invention to the details shown. The truckV body I may be pivotally'mounted as at 2 so that the body may be tilted to a position like that shown in Figure 1 for discharging materials through the end gate 3 as indicated at 4. The truck body is preferably divided into compartments by means of one or more batch gates 5 which are pivotally mounted as at 6 to swing rearwardly when released. In dumping the contents of the truck body and the receptacles, the rear compartment isr discharged first as indicated in the drawing, whereupon the respective forward compartments may be likewise discharged, the contents passing through the open end gate 3.

In` further carrying out my invention I provide receptacles 'l which may be mounted in each of the compartments ofthe truck body. These receptacles are preferably made of sheet metal and are provided with an Vopen top end for re- 55 ceiving and discharging materials such as cement. The open end of each receptacle is provided with a cover or lid 8 which is adapted to be operated at the will of the user. This phase of my invention will be described more fully hereinafter.

The dumping receptacles 'I are each provided with suitable trunnions 9 which extend outwardly from opposite sides of the receptacle for supporting the same in a suitable bearing member carried by the side walls of the truck body. These trunnions may extend through the receptacle or may be welded to the sides thereof and define the turning axis of the receptacles. The turning axis is preferably located below the center of gravity of the receptacle, when loaded, andpreferably in a plane which may be defined as off-set rearwardly from the vertical central axis of the receptacle. The receptacle will normally assume a substantially upright position as shown in full lines in Figure 2, the receptacles being normally tilted but slightly toward the forward end' of the truck body. The movement of the receptacle in this direction may be limited by means of segment-like stops I0 which are carried near the outer ends of the trunnions 9 and which are `bolted or otherwise secured thereto. The segments I0 are so designed that when the receptacle is in the full line or upright loadingposition as shown in Figure 2, the edge I I of each segment will rest upon a projection I2 of the bearing plate I3, while when the receptacle is rotated to discharging position, through an arc of less than 135, as indicated by the broken lines the opposite edge Ill of the segment will rest upon a projection I5 on the opposite end of the bearing plate I3, thus determining the limit of movement of the receptacle in both directions but providing freedom of movement thereof between these limits. y

I have provided very"simple and inexpensive bearing and supporting members I6 for the trunnions of the receptacles whereby the receptacles may be tiltably mounted on the side walls of the vehicle body. According to my invention one simple form of such a bearing or support may consist of -a plate I6 which is formed with an upstanding portion I'I apertured to receive the end I8 of the trunnion. These plates areprovided with depending portions I9 which abut the inner side walls of the vehicle body and are bolted thereto as at 20. In order that the receptacles may be properly spaced from the side walls of the vehicle body the trunnions are provided with a series of spaced openings 2| for receiving a-bolt 22. The segment I 0 is provided with a sleeve-like portion'Z?,V which is also apertured to receive the bolt 22.l It will be seen therefore that the segment may be secured'to turn with the trunnion in any one of a plurality of adjusted positions lengthwise of the trunnion, depending upon the Width of the truck body, while at the same time the segment may be readily removed after the bearing member has been removed. It will also be noted thatthe segment is Alocated between the plate I'I and the receptacle. VIn this manner I have provided against side sway of the receptacle. y

`My invention also contemplates the provision of a cover for the-tilting receptacles which may -be readily operated by the operator to permit body.

'rightpositiom -or the'rscope of the appended claims. A z if sage of moisture into the receptacle or to prevent either part or full discharge of the contents when such discharge is not desired.

These covers 8 are preferably made of sheet metal and are provided with side members 24, 5 and are pivotally mounted close to the open end of the receptacle as at 25. Suitable handles 26 are keyed to the shaft 25 for operating these covers. The forward end of each side member of the cover is provided with a turned end 21 10 which is adapted to engage a cross rod 28 carried along one of the edges of the open end of the receptacle. Additional straps with ends similarly turned are spaced along the cover for further reinforcement. While the cover is primarily 15 pivotally mounted upon the receptacle it is also capable of a sliding movement transversely of the shortest dimension of the receptacle opened end. lThis sliding movement of the cover is accomplished by means of one or more cams 29 20 which are keyed to the shaft 425anol rotate therewith, the cams operating in bearings 30 mounted on an inclined wall 3l of the receptacle. f These rbearings* 3G are located in. such a positiony on the receptacle that when the shaft 25., hasz reached 25 substantiallyY the limit of movement toward the forward partof the truckbodytheiturned.ends 2'I` ofthe covervhave tightly engagedthe cross rod 28.
